Image Display System Host Resource Reduction via Compressed Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display systems face increased system resource requirements and longer data transmission times as display resolution increases and devices transition from monochrome to color displays, leading to decreased frame update rates.
Innovation Solution
The image display system transmits compressed data via a transmission interface and uses a display driver to decompress the data, allowing the host end to maintain lower system resource requirements and reducing data transmission time without increasing memory space or processor capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the host end stores and transmits uncompressed row data, then the display device can directly display the data, but the system resource requirements (memory space and processor capability) at the host end increase significantly
Solution Approach 1:
The patent extracts the decompression function from the host end and relocates it to the display device. The host end only needs to transmit compressed data, while the display device contains a decompression unit that handles the decompression process, thereby reducing the memory space and processor capability requirements at the host end.
Solution Approach 2:
The patent introduces a decompression unit as an intermediary component at the display device side. This intermediary handles the transformation of compressed data into displayable row data, allowing the host end to operate with reduced resources while maintaining full display functionality.
2Speed
If the host end decompresses compressed data before transmission, then the transmitted data can be directly stored in display memory, but the processor capability and memory space at the host end must be increased
Solution Approach 1:
The patent extracts the decompression operation from the host end's processor and relocates it to a dedicated decompression unit at the display device. This extraction allows the host end to transmit compressed data efficiently without requiring high processor capability or large memory space for temporary storage.
3Manufacturing precision
If the display resolution increases and the display transitions from monochrome to color, then the display quality improves, but the data amount required for storage and transmission increases, leading to decreased frame update rates
Solution Approach 1:
The patent extracts the decompression function to the display device, enabling efficient handling of high-resolution and color display data. By transmitting compressed data from the host end and performing decompression at the display device, the system maintains high frame update rates even when display resolution and color capabilities are increased.
Data Source
AI summary
There is provided an imaging system capable of reducing required system resource and increasing a frame update rate. The imaging system includes a host and a display device. The host selects to transmit compressed data or row data to the display device. When the display device identifies the row data being received, the row data is directly stored into a frame buffer for being shown on a display panel. When the display device identifies the compressed data being received, the compressed data is used to generate restored data to the frame buffer for being shown on the display panel.
